Winger Gboly Ariyibi came off the bench on Saturday to score his first professional goal as the Spireites lost 3-2 at home to Coventry City.
Ariyibi's confident low strike came with his side trailing 3-1 with five minutes to go and set up and tense finale, and while Caolan Lavery twice went close with late headers the Sky Blues hung on to claim the spoils.
After the game Ariyibi spoke about his goal, capping a good few days as the teenager also signed a two-year contract extension.
He said: "Things have come along quickly in the past two and a half weeks or so and I'm delighted to get my first professional goal, it was just a shame that we lost today.
"The gaffer just told me to push on, we had to try and change the game. I thought the ball was for Mani [Dieseruvwe] but it deflected off a defender and I was lucky enough to be there and slot it into the bottom corner.
"It was weird, I would have liked to score my first professional goal in better circumstances but I just tried to keep the spirit in the team but it was just a bit unfortunate. We had chances later on, credit to Coventry but I think we dominated the game personally."
Since arriving on the first team scene in recent weeks Ariyibi has started some games before more recently influencing matches from the bench, and the USA youth international is pushing to get back into the starting eleven.
"I spoke to the gaffer before the game and he said I'm ready to start," said Ariyibi. "It's just about getting me in and easing me into the team, I'm fighting for a place.
"We go again on Tuesday, we can't beat ourselves up about it and I'm sure we'll start off well then.
"We've had setbacks and we've been through a lot this season, so I think we'll be ready to go on Tuesday."
